For teaching purposes I'd rather welcome parts of the STL, because people 
would learn STL as well. Of course, the resulting class should behave 
exactly as the original in ::std as far as it's implemented (e.g., have the 
same error handling).

But if the students do not know complex numbers at all I'd not recommend 
that.

What about modulo operations? You could start with the modulo as a private 
constant and if you plan to teach templates, later, you can reuse your 
example and make it a template parameter.
